Google is adding a new feature to some Android phones that can speak to an emergency operator on your behalf when you call 911. During an emergency call, three new buttons — "Medical", "Fire", and "Police" — will be available in case you're unable to speak. They will initiate a voice message to the emergency operator that explains the nature of the emergency and your current location. After you activate the service, you can always speak directly to the operator as well. The feature will become available in the US over the coming months, starting with Pixel phones.
